I am only using one of the two analog inputs to the video chip, what do I do with the analog input pins on bank 1. Do I ground them or leave them unconnected? I am referring to RAIN1, GAIN1,BAIN1,SOGIN1,VSYNC1,HSYNC1.


Also, The datasheet recommends Fair-Rite #2508051217Z0 in series with the analog input video signals. These inductors are 0805 are there any smaller size inductors that have been tested and recommended?
